摘　　要：The extracellular enzyme activities of sclerotia-forming and nonsclerotia- forming single spore strains of Morchella conica and M. crasspies were determined and compared. The non sclerotia-forming strains of M. conica exhibited higher aver- age activities of protease, catalase and xylanase but lower laccase activity than those of sclerotia-forming strains. However, the differences did not reach significance level. The soluble amylases activity of M. crasspies was significantly higher than that of M. conica, while the mean activity of other enzymes had differences between them, but the differences did not reach significance level.对尖顶羊肚菌产菌核及不产菌核单孢菌株、粗柄羊肚菌单孢菌株的胞外酶进行了测定和比较,得出了尖顶羊肚菌单孢菌株胞外酶活性特征,且不产菌核菌株的蛋白酶、过氧化氢酶和木聚糖酶的平均活性高于产菌核菌株,而漆酶活性却低于产菌核菌株,但未达到显著差异;粗柄羊肚菌胞外可溶性淀粉酶活性极显著高于尖顶羊肚菌,其它酶活性在均值上有差别,但都未达到显著水平。
